Nothing philosophically significant here.* Just another way in which Botox --one of the most potent poisons around-- is useful for more than just destroying the expressiveness of people in LA's faces.
Abstract: Botulinum toxin type A (BoNT-A) shows significant promise in the management of a variety of headache types including migraine, chronic daily headache, tension-type headache, and other head and neck pains. Confirmation of efficacy still awaits the report of well-controlled double-blind placebo-controlled trials; however, a mounting body of evidence suggests that BoNT-A is effective, well-tolerated and safe for the management of many headache disorders. In this paper, I review recent evidence on the efficacy of BoNT-A, and also report my personal experience with the treatment in over 600 headache patients.

Seriously though, since the etiologies of many headaches are so mysterious, any widely effective management technique will lessen a lot of suffering (N.b., people with some headache disorders --e.g., cluster-headaches-- are particularly prone to suicide).
* Okay, one small philosophical note. Its worth thinking hard about why headaches are often so much worse than many sharp and acute pains (e.g., a badly stubbed toe). Two hints:
(1) It is very difficult to disassociate from a mildly severe headache since we usually experience ourselves as being 'in our heads'.** It is comparatively easy to disassociate from a badly stubbed toe or a hammer-smashed finger.
(2) At a fairly low level of intensity, headaches can have a huge negative impact on our lives and well-being. A migraine makes it hard to carry on a civil conversation and can (temporarily) destroy one's capacity for the pursuit of long-term projects and close personal relations.(This becomes more interesting when one believes, as I do, that such effects on one's life can be intrinsic properties of a pain)
**Pace Aristotle, who seems to have believed that the heart is the seat of the soul and (so I've been told) experience.
